ATOMIZER.

SPECIFICATION forming part ofLetters Patent No. 371,615, dated October18, 1887.

Application filed January 22, 1587. Serial No. 225,222. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK JAMES MITCHELL, a subject of the Queen ofGreat Britain, and a resident of New York city, in the county of NewYork and State ofNew York, have invented certain new and usefulperfumed; and the objects of my improvements are, first, to provide ameans for atomizing the. substance, powder, or liquid into the place,and affording facilities for atomizing by the use of force or poweroriginating at any distance desirable from the place to be deodorized orperfumed; second, to do both these things in a cheaper, better, and morelasting way than heretofore, and by means which will not easily get outof repair; third, to keep the powder,- substance, or liquid of a uniformstrength. I attain these objects by the mechanism illustrated in theaccompanying drawings, in -which--- Figure 1 is a view of the entireapparatus, showing the vessel containing liquid to be atomized and itsadjuncts and the cylinder of the air forcing or compressing device insection, the air forcing'or compressing device being attached to andoperated by a door. Fig. 2v is a perspective view of the disk and pipesof the atomizer.

Similar letters refer to similar parts throughout the several views.

In the place to be disinfected, dcodorized, or perfumed I place orattach the vessel 0, containing the liquid disinfectant or perfume to beatomized into the room. The pipe I) of the atomizer has its one endimmersed intheliqu'd and the other end in close proximity to the e l ofthe air-pipe c of the atomizer.

The pipe 0 is by a pipe or tube, G, (pref 5 ably a rubber tubc,)connected with an air tion from the/vessel.

vided with pivots p p, on which the cylinder can turn. Piston B isconnected with the door itself by the bracket r, and moves on the pivota, running through the piston near its end, and 6 0 the pivot s is heldin place and moves in the projections t t of the'bracket r. The pistonis also provided with the section a, which forces air out of thecylinder A through the pipe 'v,

to which the air-tube C is attached. When the piston is drawn out of thecylinder by the action ofthe door, it sucks air into the cylinderthroughthe pipe 0 0 v, and when-the door is closed the piston forces the airout through the same pipe, 12 C c, and so atomizes t-hcliquid in thevessel a into the circumambient air. I also use the disk d, having aslot or cut, e, which disk prevents evaporation, and the slot, togetherwith the funnel f, allows the liquid which is drawn out and not atomizedto flow down into the vessela again. The disk performs the veryimportant office of keeping the liquid at a uniform strength by notallowing too much evaporation to weaken it. This evapo- .ration andconsequent weakening has been a great defect with othcr deviccs fordisinfecting and perfuming where the whole surface of the liquid hasbeen exposed to the air.

The funnel f has a flange, m, and by means of the removable screw w, Iscrew the flange of the funnel down onto the disk e, thus keepiug theflange tightly in place, and also presslug the disk down closely toprcvent evapora-- This screw works in the screw-thread in the neck gv ofthe vessel a. The screw is made short enough so that its upper L endwill be below the opening a of the funnel.

I prefer to use this screw insteadof making the screw a part of thefunnel itself, so that the hole a is-always on the side nearest the tube0, which is more convenient, and which ;I could "i not depend upon ifIwere to screw down the funu el tightly by ascrcw which were part ofitself.

I prefer to solder the disk (I and the pipes c and b together. 1 putthem in place by taktoo ing hold of the funnel and the screw, which andwith the other hand I run the straight end of pipe 0 perpemlicnlarly upthe funnel, and when the end h of pipe 0 gets near the opening a of thefunnel I turn that pipe horizontally and run the end h through thatopening. Then, holding the funnel and pipes in that position,

I immerse the pipe 6 into the liquid, while at the same time I place thefunnel within the neck 5 ot' the vessel 0, and as the disk is solderedto the two pipes b and c the disk rests in place by so immersing pipe b.Then I screw the funnel and disk both down tightly by the In theaccompanying drawings I show only one way of accomplishing ,ihe objectsof my improvements; but I also claim all substantial ly similar wayswhich would be necessitated by a, different motive power than a neardoor. Different atomizers or difi'erent air forcing, or compressingdevices might be also used without departing from my invention, as thesubstance 01 my invention is having an air forcing or compressing deviceattached to some movahlc object, and by means of a pipe or tubeconnctteC with an atomizer operating, on liquid ti; atoznize it into anyplace to be disinfected or pertained, and even if the place into whichthe disinfectant, antiseptic, deodorizer, r per [unitis to be atomizedis at a great distance from the movable object; so that it in thehonseor neighborhood any door or other movable thing (whether on thesame door or on a lower or higher floor) is specially adapted, from itsfrequent use, to be connected with the atomizer, its motion can beutilized for my improvement.

'Prior to this invention i; was accustomed to operate perfnming anddisinfcctim devices at aslight distance by the use oi wires overpulleys; but these wires lose some force over each pulley on -which theyare strung, so that they cannot beinadc to ope ate when. stretched atsome longer distance from thcplace tn Zimmerated upon, as they requireso many pnheys that they are unreliabl and, in fact, can only be usedforveryshortdistances. lit-sides, the tension isliltclytogtt themoutol'oider. This is not the case with my improvement, as myimprovement, lltflllg pmmniatic, simply cmploys air as the means tooperate with \Vliat I claim as my invention, and desire to secure byl'n-tlr-s Patent, is-
